Abstract
A silence oxygen flowmeter comprises a body, an air inlet connector, an air outlet connector, a flow displaying pipe, an adjusting button, a humidification bottle and an overflowing pipe. The silence oxygen flowmeter is characterized by further comprising a shielding cover upper shell body and a shielding cover lower shell body. The small-opening end of the shielding cover upper shell body is connected with the body, the large-opening end of the shielding cover upper shell body is connected with the shielding cover lower shell body, and a formed sealing space wraps the humidification bottle. After the shielding cover upper shell body is connected with the shielding cover lower shell body, a formed sealing structure effectively and further insulates and reduces the noise led out from the humidification bottle, the silence of the oxygen flowmeter is achieved, and the problem that oxygen inhalation people and other patients in the same ward cannot fall asleep easily caused by the noise produced by an oxygen flowmeter in the prior art is solved. Meanwhile, the silence oxygen flowmeter has the advantages of being simple in structure, easy to manufacture, small in occupied space and low in cost.
Description
Technical field
The present invention relates to a kind of quiet oxygen flowmete.
Background technology
Oxygen uptake is oxygen intake, is clinical methods for the treatment of commonly used.Oxygen uptake is used for correcting anoxic, improves the level of arterial partial pressure of oxygen and oxygen saturation, promotes metabolism, is one of important method of the multiple disease of auxiliary curing, as respiratory failure, and chronic bronchitis, asthma, cerebrovascular disease, coronary heart disease etc.Also may there be the microcirculation metabolic disorder in the not obvious person of clinical anoxic symptom, thereby needs oxygen uptake, as patient, massive haemorrhage shock patient before and after some operations, patient such as fetal heart sound is bad or stages of labor is long during childbirth.The method of oxygen uptake has three kinds: nasal obstruction and nasal tube oxygen inhalation method, mask oxygen-inspiration method, per os oxygen adsorption method.
No matter adopt which kind of oxygen uptake method, when patient's oxygen uptake, all need to use oxygen flowmete.The structure of the oxygen flowmete of prior art comprises as shown in Figure 1: body, inlet suction port, air outlet adapter, flow display tube, adjusting knob, humidification bottle and escape pipe.The course of work of oxygen flowmete is: oxygen enters body through inlet suction port, after entering humidification bottle and pure water contacts, escape pipe flows to the patient of oxygen uptake again through air outlet adapter, the effect of adjusting knob is the flow of regulating oxygen, and is shown by the upper-lower position of steel ball on the flow display tube.
The problem that the oxygen flowmete of prior art exists is: when oxygen with understand the generation bubble after pure water in the humidification bottle contact, after breaking, bubble produces very big noise, daytime, this noise was not discovered under covering of environmental noise, but evening is after environmental noise reduces or disappears, it is very big very ear-piercing that this noise becomes, and had a strong impact on the sleep of oxygen therapic patient and sleeping with other patients in ward.
Summary of the invention
The object of the present invention is to provide a kind of quiet oxygen flowmete, the humidification bottle outside at the oxygen flowmete of prior art installs a cage (comprising upper shell and lower house) additional, to in humidification bottle, conduct the further isolation of the noise that and decay, quiet to realize.
Technical scheme of the present invention is achieved in that a kind of quiet oxygen flowmete, comprise body, inlet suction port, air outlet adapter, flow display tube, adjusting knob, humidification bottle and escape pipe, it is characterized in that, also comprise cage upper shell and cage lower house, one end of described cage upper shell is connected with body, the other end of described cage upper shell is connected with described cage lower house, and the confined space of formation is coating humidification bottle.
Preferably, the medial surface of the big openend of described cage upper shell and little openend has following at least a structure: bulge loop, groove, screw thread, the smooth face of cylinder; Perhaps, the lateral surface of the big openend of described cage upper shell has following at least a structure: bulge loop, groove, screw thread, the smooth face of cylinder.
Preferably, the quantity of described bulge loop or groove is 2.
Preferably, the medial surface of described cage upper shell has the projection of regular distribution, is used for the sound wave that reflection is transmitted from humidification bottle; Perhaps, the medial surface of described cage upper shell has the projection of stochastic distribution, is used for the sound wave that reflection is transmitted from humidification bottle.
Preferably, the housing of described cage upper shell is cavity structure.
Preferably, the medial surface of the openend of described cage lower house has following at least a structure: bulge loop, groove, screw thread, the smooth face of cylinder; Perhaps, the lateral surface of the openend of described cage lower house has following at least a structure: bulge loop, groove, screw thread, the smooth face of cylinder.
Preferably, the quantity of described bulge loop or groove is 2.
Preferably, the medial surface of described cage lower house has the projection of regular distribution, is used for reflection
The sound wave that transmits from humidification bottle; Perhaps, the medial surface of described cage lower house has the projection of stochastic distribution, is used for the sound wave that reflection is transmitted from humidification bottle.
Preferably, the housing of described cage lower house is cavity structure.
Preferably, the big openend of described cage upper shell has seam; Perhaps, the little openend of described cage upper shell has seam; Perhaps, the big openend of described cage upper shell and little openend all have seam.
Preferably, the openend of described cage lower house has seam.
The invention has the advantages that, the oxygen flowmete of prior art is not structurally done any change, only need to increase cage upper shell and cage lower house, the cage upper shell is with after the cage lower house is connected, the hermetically-sealed construction that forms will conduct the further isolation of the noise that and decay effectively in humidification bottle, realized the quiet of oxygen flowmete.Simultaneously, the present invention has simple in structure, is easy to make, and it is little to take up room, the characteristics that cost is low.
